Nord Cryo Line RF Cables Available

Nord Cryo Line RF Cables are designed for both room-temperature use and use inside the cryostat. All cables have an impedance of 50 ohms, with reflections below −20 dB up to 14 GHz.

The RF Cable category currently includes four product types:

1. Nord Cryo Line - Cryogenic Superconducting Coaxial Cables

Superconducting and thermally insulating cryogenic cables, ideal for high-frequency flux control lines. Superconducting behavior at DC and low frequencies helps eliminate Joule heating along the wiring chain. Made with niobium-titanium (NbTi), with a critical temperature of 9 K.

2. Nord Cryo Line - Cryogenic High-Thermal-Conductivity Coaxial Cables

Designed for use within a single temperature range, for example at the MXC stage, to connect cryogenic devices to each other and maintain good thermalization. These cables are hand-formable for neat routing, non-magnetic for compatibility with sensitive quantum devices, and available with SMA, SMP, SMPM, and MMCX connector options. Typical lengths range from 5 cm to 100 cm, cut to requirement. Diameter 0.086”.

3. Nord Cryo Line - Cryogenic Low-Thermal-Conductivity Coaxial Cables

CuNi-based cryogenic cables with low thermal conductivity, designed for installation between different temperature stages in the cryostat. Fully non-magnetic and delivered with a formed loop for easy installation between fixed plates. Lengths range from 50 cm to 250 cm, measured end-to-end between connector interfaces. Diameter 0.047”.

4. Nord Cryo Line - Room-Temperature Coaxial Cables

High-thermal-conductivity, hand-formable, and non-magnetic cables for routing between control electronics and the cryostat, or between electronics units within or between racks. Sized at 0.141” with SMA-SMA connections, with lengths from 10 cm to 20 m. Stock lengths include 25 cm, 100 cm, 150 cm, and 200 cm.
